In reality, the knowledge that Britain had deciphered Germany’s codes should have remained a secret for several more decades. Regardless of the reasoning, staying ahead of the opponent, even in a time of peace, provides tactical advantages on many fronts. I believe, however, that pride and competition with the United States ultimately lead Churchill and the British Royal Navy to publish the information.
A gruesome war that tore through most of Europe had finally come to an end. It was a time of celebration for the countries that had triumphed. Publishing the findings showed the military tact that had been used by Britain and their ability to triumph their foes. It proved the resourcefulness of the country and allowed for a sense of pride to be instilled in Britain’s citizens. This also allowed Britain to show that they had been vital in the victory of the war. To some, it looked like the United States had joined the war efforts, intercepted messages, and swiftly ended the war in a year. It allowed British citizens to not feel like their ally had done everything.
Although Britain allied with the United States during and after the war, superpowers in the world are still each other's competitors at the end of the day. Across the ocean, “Herbert Hoover had been elected President and was attempting to usher in a new era of trust in international affairs” (Singh, 1999, p 141). After the war, in several countries, a lack of transparency between the government and citizens was felt. Since the United States was appearing to be more open with its’ citizens, Churchill most likely felt pressured to respond in some way. By publishing his findings, he was able to show that by keeping some secrecy during the war, Britain was ultimately able to keep the upper hand on Germany. Now, the information was viewed as not being pertinent and it was a good way to loop the citizens in.
If Britain had not revealed this information publically, it is possible that the Enigma machine would not have been utilized by Germany. After all, many were hesitant to adopt new forms of encryption due to cost and ease of use; WWII potentially could have been a far different war.
